Brave, brave, brave, brave Sir Cumference... (sing it with us!)

Sir Cumference isn't the most famous knight. In fact, we'd say he's a figure on the perimeter at best. And after all these years, we're afraid he might have developed a bit of circular thinking. Sir Cumference may be tilting... well, around windmills, as it were. We mean - look at him. He's clearly been πD on his journey. Fortunately just like a squire in the olden days, we can help him with that. In fact, we have a fresh t-shirt right here for just such an occasion.
